What Is EPC Gen2 v2?
Is this a standard? What does it mean?
EPC Gen 2v2 is an update to GS1's Electronic Product Code (EPC) air-interface protocol standard for passive, ultrahigh-frequency (UHF) RFID tags. It provides a series of features intended to improve security and deter the counterfeiting of tagged products, by enabling the authentication of a tag or reader, and includes privacy features for consumers, as well as a way for embedded tags to identify themselves as such to an interrogator. Gen2v2 also enables a tag's user memory to be partitioned into multiple files. Tags compliant with the new standard can be used for electronic article surveillance (EAS). Gen2v2 was ratified on Oct. 30, 2013 (see GS1 Ratifies EPC Gen2v2, Adds Security Features, More Memory).
